I agree with checking your WINS servers. If you have multiple WINS servers make sure both are clearing out the Source server after the failover.
Todd >>> [EMAIL PROTECTED] 02/13/02 09:26AM >>> I had a somewhat similar problem. When the failover computer would take over, the alias would have trouble with my WINS server. If I removed the old (i.e. dead) server from WINS, and let the new (Failover) server register itself, I think it was fine (IIRC). That might not be your exact problem, but hopefully it points you toward a solution. -Jim Jim Holmgren MCSE, CCNA [EMAIL PROTECTED] Network Engineer Advertising.com We bring innovation to interactive communication.

The issue looks to be that the #2 server doesn't have a user account for the domain? Is the issue that when you reboot the 2nd machine and go to do an admin login? -----Original Message----- From: Jim Holmgren [mailto:[EMAIL PROTECTED]] Sent: 13 February 2002 17:00 To: MS-Exchange Admin Issues Subject: RE: Double-take failover Double-Take works fine with Exchange 5.5, although I admit I do not know the cause of this particular problem, I don't think it is specific to Double-Take. Our list host (Sunbelt Software) sells this fine product. http://www.sunbeltsoftware.com/product.cfm?id=111 and NSI includes Exchange-specific configuration details. I may be wrong, but I thought I read at one point where it had been tested with Exchange by Microsoft. -Jim Jim Holmgren MCSE, CCNA [EMAIL PROTECTED] Network Engineer Advertising.com We bring innovation to interactive communication.

REPEATE DO NOT!!! use any clustering product, backup product, server mirroring product UNLESS IT HAS BEEN CERTIFIED BY MICROSOFT TO BE COMPATABLE WITH EXCHANGE!! Even Microsoft's own clustering product doesn't work infallably with Exchange. I doubt that this product has been tested with Exchange. John M. -----Original Message----- From: Jeff Pace [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 13, 2002 11:21 AM To: MS-Exchange Admin Issues Subject: Double-take failover Hello all, I have two exchange servers that are running double-take. Everything is fine and dandy until I test the failover. The #2 machine takes over the identity of the #1 machine. This works fine, what doesn't work is the login to the domain. I lose my domain login and in result cannot pass email over the network. When I try rebooting the #2 machine (now #1) the domain says the account doesn't exist. I have inherited this network and the domain was setup already. I don't know much about how the domain works. Servers = NT4.0 compaq proliant SP 4 exchange = 5.5 The odd thing about this situation is that I aslo have two other servers running double-take, although not on ecxhange, and they work fine when failed over and failed back.
